1'0 a whom it may concern:

Be it known that we, JAMES TIMMS and JAMES O. TIMMS, residents of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Car-Couplings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in car-couplings, the object of the invention being to provide improved mechanism for unlocking the pivoted knuckle of couplers of the J annoy type and also throwing the knuckle open; and the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1. is a view in vertical cross-section illustrating our improvements. Fig. 2 is asimilar view showing the locking-pin'in lock-set position and the device ready to force the knuckle open. F 1g. 3 isa viewof the bar 11; and Figs. 4, 5, 6, 7, and 8 are views illustrating modifications. 1

1. represents a couplinghead,' 2 a lockingpintherein, and 3 the tail of a pivoted or swingingknuckle secured against swinging movement by the locking-pin. The lower end of the locking-pin 2 when in locked position projects through an opening in the bottom of the coupling-head, and the pin is made with a shoulder 41 near its lower end. to rest on. a ledge 5 atthe bottom of the head 1 to support the pin 2 in lock-set position with the recess 6 in the pin in line with the knuckletail 3 to permit the knuckle to be swung open, and the swinging open of the knuckle-tail will move the pin from lock-sct and into position to fall and lock the knuckle when the latter is closed.

A lover 7 is pivoted between its ends to a depending lug 8 on the bottom of head 1, and its heavier 0nd projects below pin 2 and is made with an upwardly-curved extreme end, asshown at 9, to engage the curved lower en 1 of pin 2, so that when'the lever is swung 0 its fulcrum the curved end of the lever 7 will not only elevate pin 2 to unlock the knuckle but will also force the pin over to one side due to the cam action of the lever against the pin to bring itsshould'er 4 over the ledge 5 and support the pin in lock-set position. The

other end of lever 7, which is approximately vertical, extends up beside the .head 1 and projects through an elongated slot 10 in a push-bar 11, the latter being supported in an opening 12 in the wall of head 1- and project- 'ing into a recess 13 in the rear of knuckle-tail 3, provided to receive the same. The outer or free end of push-bar 11 may be supported in any approved bracket or bearing at the end of the car, as this bar 11 hasno vertical or pivotal movement, its only movement being longitudinal, and it preferably terminates near the side of the car in convenient reach of an operator. The upper end of lever 7, which projects through the slot in bar 11, is enlarged and given the peculiar curvature or contour shown at 15,.which insures the retention of the lever in the slot '10 and prevents possibility of accidental disconnection.

The operation of our improvements is as follovs: The bar 11 is first drawn outward, wiiici motion, due to the fact that the upper end of lever 7 projects through the slot 10 in the bar 11, will cause said lever to pivot and its heavier lower end to rise, elevating pin 2,

and owing to the cam action of the curved or enlarged end 9 against the curved lower end of pin 2 will force the'pin over to one side to bring the shoulder 4 on the pin over the ledge 5 and support the pin in lock-setposition. The push-bar 11 isthen forced inward, and its, inner end will engage the tail of the knuckle and force the knuckle open.

In the modification illustrated in Figs. 4, 5, and 6 the upper endof lever .7 is made with a slot or opening .16, the upper portion of said opening being larger than the lower portion 17, and the push-bar 11 is provided with a contract'ed portion 18 with shoulders 19 at the opposite ends'of the contracted portion 18. Thebgr 11 can be readily inserted in the enlargedopening 16, and the contracted portion willfall into the contracted part 17 of the said' opening, the shoulders 19 compelling the lever 7 10 be swung by the push-bar, and the opposite sides of the lever at the contracted opening'17 are cut out, forming receptacles or recesses for the shoulders 19 on bar 11 to prevent upward 'movement of the bar 'during the normal operation of the improvements; or the lever and pushrod may be constructed to interlock, as shown in Figs. 7 and 8, in which the lever is provided with an elongated slot 20 to receive the flattened end of the push-bar, and the: latter is provided with a contracted circigilmportion 1 6 stanliiilly the (lizuneti. oi the Film, w when the contra-sled pcirtioii 2i is in Lin, i and the rod given a qimrtienlu'rn the i" lever will he niovably' coupivd togetl i The push-rod 1.! is supp position, i that; ihe i Will in \i? in (finally h gravity "7 :t the i-znum and remain in such pobi icn ready in gm the knuckle open when (lesi @zl.
